BETA PHOTO: Big Dihedral - sector 4 Bramois


Real dihedral climbing sustained, with a variety of thoughtful moves.
Despite the Silver Lake cliffs looking like slabs from the parking, much of this open book / dihedral is full vertical.

Lots of moss as of 2016. The quality of the route should improve as it gets cleaned and climbed more.

Pitch 1: Start a few feet right of the dihedral, under a deep roof. Up a bit under the roof, then step across left into the dihedral. Up to the top of the dihedral / open book, perhaps sometimes using a handhold out on the face to its left. Finish on wide ledge with a large dead tree stump. (5.7+ 75 ft)

Pitch 2: Up the mossy slab to the top of the cliff. (5.3 35 ft)

Since the line of both pitches is roughly straight up, they could easily be linked.

On the other hand, the special dihedral feature is finished after P1, and it's tricky to make a single rappel from the top of P2 because the rope could get stuck on the big tree stump. So quicker to rap off after doing only P1.

descent: currently no established rappel anchors (as of 2016). So either bring your own equipment to leave behind on a rappel descent. Or walk/scramble off north (right) - a bit tricky, class 3-4 if take the more direct way. Class 2-3 if first go higher (and a bit left) before going down around north side of cliff.

warning: The rock on and near this route has not been climbed much yet, and some of the rock is still breakable and loose -- so the belayer and other people should stand far away from underneath the climber.


At the bottom of the obvious big dihedral (like a book open at a 90-degree angle) around center left of the main wall.

No fixed hardware for top anchor or for leading.

Top-Roping: For ideas about how to get access to set up top anchor, see Description page for Bramois sector.

Above P2 is a "thread" opportunity where a large rock leans against a wall. Also a mature bush with a thick trunk. Problem with setting top anchor above P2 is that when pull the rope down afterward it could get stuck on the tree stump on the big ledge at the top of P1. A possible approach for quick exit would be to first rappel down to the wide ledge at the top of P1 and set the top anchor there.

Protection for Trad leading is unknown.
